Question
**Genetic Experiment with Peas**

In a genetic experiment with peas, one sample of offspring was analyzed. The sample consisted of 415 green peas and 163 yellow peas.

**Tasks:**

**a. Construct a 95% Confidence Interval**

- Calculate a 95% confidence interval to estimate the percentage of yellow peas.
- Express the percentages in decimal form.
- Two input boxes are provided to fill in the lower and upper bounds of the interval.
- Remember to round your answers to three decimal places as needed.

\[ \text{Lower bound} \, < \, p \, < \, \text{Upper bound} \]

**b. Analysis of Expectations**

- Given that it was expected for 25% of the offspring peas to be yellow, determine if the results contradict this expectation.
- Options:
  - Yes, the confidence interval does not include 0.25, indicating that the true percentage could not equal 25%.
  - No, the confidence interval includes 0.25, indicating that the true percentage could easily equal 25%.

*Select the appropriate response based on your confidence interval calculations.*

**Notes:**

- The sample was analyzed, expecting that 25% of the offspring peas would be yellow. The purpose of this analysis is to verify the outcomes against the expectations.
- Confidence intervals offer a range of values that are plausible for the parameter being estimated, helping to determine if observed data aligns with theoretical predictions.
